To all whom itmay concern: v

Be it knownptha-t I, GEo eEF. MoGAI nY,

a citizen of the United States, residing at Providence, in the county of Providence and State of Rhpde Island, have invented certain new and useful'linproveinents in B raiding Machines, of which the ifollowing'yis a specification. f

This invention relates to improvements in braiding machines more particularly to the so-called rotary typepf ,bra derun which machine.

A further object of the invention isto position the yarn-tension weight standardsof both sets of supplies onacorresponding incline to the common axis about which-1 they revolve and rotate these carriers inopposite d rections and 111 different planes, whereby the yarn tension devices ,of {both sets may be so positioned thatyunder' action of cert,

trifugal force an equal tension will beleiv erted on bot-hsets of supplies, which is 'eS- sential in. the production of a uniformproduct.

The nature and advantagesof tl1e',1nv'ention willfbe'be-tter understoodwhen the following detail description is taken in connection with the accompanying drawings,

the invention residing in .tliecombination and arrangement of parts as claimed.

In the drawings forming party of this specification, like numerals of reference indicate similar wherein y F igurel is a side elevation of the machine partly in section.

Fig. 19 is a perspective view of the shuttle member to which the cop-carrying tube is connected.

with reference to the drawings, 20 designates the base-plate of themachine, which is supported on usual legs 21. On this baseplate are upright frame rods 22 which support the outer ring or member of the raceway plate 23 and also support the upper frame members 24:. On this base-plate 20 I have fixed a tubular standard 25 to which is secured the inner section 26 of the raceway, which section is provided with alternate spaced-apart shuttle guiding surfaces, 27 which, as shown in Fig. 2, are formed. on the arc of a circle and cooperate with the alternate shuttle guiding surfaces 28 of the outer raceway member 23 to form a ring for the support of the traveling shuttle (presently described). A space 29 being provided between the adjacent ends of the inner and outer grinding members, through which the yarn 30 is caused to pass as it leads from each of the lower supplies 31 through their respective guide eyes 32 to the point of braiding 33 and is carried in a serpentine path alternately over and under the shuttles and the upper series of supplies carried thereby as illustrated in Fig. 4.

On the plate 3a, which is mounted to rotate on the ball bearings 35, actuated by the driving pulleys 36 through the shaft 37, clutch 38 and gears 39 and 10, is mounted the lower set of supplies to be rotated in 5 one direction. Each supply of this set comprises a base 41 which is mounted on the revolving plate 3st and whlch base is arranged to support a tension welghtguide bar 12 which extends in an upward direction on an incline to the common axis about which this set of supplies rotates. The upper end of this weight guide is arranged to support a spring pressed latch 43 for engaging the spool ratchet 44 of the bobbin 31, into the lower end of which spool projects a short spur -16 which extends into the hole through the spool to retain its lower end in position. The usual weight 47 being preferably employed to slide on the weight guide to apply the required tension to the yarn.

I The shuttle member 48 has a central web 49 connected to the upper and lower pairs of flanges 50 and 51 all of which are formed on the arc of a circle necessary to engage and slide on the raceway sections as the shuttle is driven in a circle.

Below this raceway-engaging portion of the shuttle I have formed a thread-guiding plate 52 which is pointed at the front end at 53 and preferably rounded at its rear end 54: for the purpose of engaging and guiding the yarn either over or under the shuttle.

On the under side of this guide-plate I have secured a tubular yarn guiding and protecting member 55 to the outside of which is secured the weight guide 56, a Weight 57 being mounted to slide thereon. A yarn guide-hole 58 is provided to permit the yarn 59 to pass out, down around the weight. 57 and up through the tubular opening 60 in the shuttle head.

\Vithin this tube I have mounted a bobbin 61 having a ratchet spool head 62 at its upper end engaged by a spring-pressed latch 63, the end 64: of which latch extends out through the opening in the side wall of the tube into position to be engaged by an upward throw of the weight 57 to release the spool when more yarn is required. This spool is held in position on the central rod 65 by a latch 66'which is pivoted in the end thereof.

The raceway guides 27 and 28 are set on an angle so as to receive the shuttles. 48 and permit them to support the upper set of yarn supplies below the raceway and on an incline, the angle of which inclination is substantially the same as that of the supplies of the lower set and this upper set of supplies overlap the lower set and are so positioned that the tension weights of both sets shall be substantially equidistant from the common axis about which they both rotate so that centrifugal force shall act the same on both sets of weights as they revolve at the same circular speed, which uniform action on the tension Weights, produces a uniform tension on both sets of threads which uniform eflect cannot be obtained where weights are positioned at different distances from the center around which they rotate. It will be noted that the inner surface 27 (Figure 3) of the raceway guide 27 is inclined at substantially a right angle to the axis of the yarn supplies; the outer surface 27" may be also inclined in this manner. This inclination of one or both of the. surfaces mentioned assists materially in the reduction of friction. 28' is inclined in substantially the same plane as the shuttle, and substantially parallels the axis of the yarn supplies. Moreover, the entire track forming the raceway is ar ranged in a plane inclined at an angle to the common axis of the shuttles, as above mentioned, and illustrated clearly in Figure 3.

In order to drive this upper set of yarn supplies in. a direction opposite to that of the rotation of the lower set of yarn supplies, I have provided a tubular shaft 67 which is rotated from the gear 39 through the gear 68 to the upper end of which tubular shaft I have connected the drive-dog plate 69. This guide plate is best illus trated in Figs. 7 and 8 as being provided on its under side with a multiplicity of radial slots 70 in which the drive dogs 71 are guided, the ends 72 of these dogs being adapted to engage the recesses 73 in the The top surface shuttle, fla and p e e esse yoked. t h r t n fiaj l lby e plat 7 hic ip ie is pi'i oted'atifi mule u'iidei side of the d9 i e P tew: ne of. 2 1 ipaii xef. he i drivehdogs is proyided 'witl a guide 1*ol lj 76 i fl t id dqwnfi fie the um .5; eve a in mi -m "Pla e 7 hfr'e infe b t trated in Fig. 14, each panidrive dog s is: TecipIOCatedfin and ioiitfa't the. propelf time and atthelpointsiwiin tl i s c aflp; to 'pel niit the. yarn ffointh'e' lower; snpplyl t o' pass the shuttle of the? nppeisnpp ly jw'ithont ,atj an y tune entirely d sengag ng tlie dr i e flQlQ thQl.
